DUMP-CAR.

Specification of Letters Patent.

Patented July 16,1912.

Application filed October 10, 1911. Serial No. 653,835.

To all whom it they concern:

Be it known that I Tnoxus B. lil..\(l(- nt'ux, a eitizen ot the lfnit'ed States, residing at lios Angeles. in the eounty of Los Angeles and State of California. have invented a new and useful Dump-Car. of which the following is a s 'ieeitieation.

This invention relates to dump 'tll'S. partieularly to dump ears having int-lined hot toms and doors at the sides thereof for permitting the eargo to he, dumped. and has for its ohjeet to provide eertain novel improvez tents in ears of this eharaeter. espeeiallv over the ear diselosed in Patent No. 858.044, issued .lulv 2. 1907.

One of the improvements (-ontemplated h v the present invention is to provide an tor releasing the side doors ot the ar. and turther. to release the respertive side doors one at a time \v'hereh) a partial dumping of the'eargo ran he et' l eet et l.

, To this end the. invention resides essentiall v in a ear havine a plurality of doors hinged along one side thereof. tongues projertingr trout the tree edges of the said doors, a har slidahle along: the respeetive side (it the ear. and hooks seeuredv along the outer side of the said har. the said hooks heing ot ditl'erent lengths and arranged to engage the tongues ol' the respective doors to retain same hetween the hooks and the har. whereh v upon the har heing'slid the respt-elive doors are liherated one at a time as the har assumes ditl'erent positions.

In the present diselosure the ear is shown as provided with a plurality of doors alone hoth sides thereol'. hut it is understood that the rar tna he so t-onstrueted as to dtnnp on side only in \\'llltll event the doors would he arranged along the respeetive side o! the ear. I! is also understood that various alterations in the details ot the invention may he resorted to within the seope ot' the appended elaitus without departing l'rom the spirit, of the invention.

The invention is illustrated in the :t 't'()lll partying drawings. wherein similar reler enee eharaeters indieate similar parts. and wherein Figure l is a side elevation ot a ear etuhotlyingg the invention. parts hroken away and the .2 l.

Fig. I3 is a lragrutental view in perspeetive 'showine' one ol' the door tongues engaged l l l l l l l l ii l trurks ol' the ear heinn' removed. a station on the line :4 ot Furv l. j

doors Tare set-tired a pair of hars 1t) whit-h have the lower ends thereof ollset outwardlv and depending helow the lower or tree edges ot the said doors to form tongues 23.

Along each side of the ear is arranged a longitudinal slidahle har l t. the same heine' arranged helow the tree edges of the doors T and slidin;- against the hase t of the ear within the elips 2t seeured to the partitions t andthe ends 5). To 'aeh har I3 is riveted or otherwise set-tired a series ot hooks 2.1.121 and 21", the respeetive sets ot hooks heing ot' ditl'erent lengths and lltllhL' arranged to engage the tongues 21% of the respective doors '4' to retain the doors in rlosed position. 'lhese hooks Z1, 31" and it" are preferably t'ormed from short pieees ot' har metal of a width equal to the hats l3. and have the hooked ends thereot eurved outward in order to readily direet the. tongues into the hooks. as designated at 20.

lielow the hase t is mounted a e vlinder i having the piston 22 therein and an air supply pipe it) is ronneoted to the said eyl iuder. 'lhe piston rod t whirh is ronneeted to the piston ear and is slidahlv mounted in the guides lever ll is pivoted at the said end ol' the ear upon hearings l! and has the elongated slots I l and I?) in the upper and lower ends thereot respeetivelv. The respet'tive har t-i is provided with a pin 17 en nagii'ig in the slot I-l ot' the lever ll. while the piston rod l8 is provided with a pin to engaging in the slot 1?) ol the said lever. wherehv when the piston rod is slid a wa v from the lever ll the har 13 is eaused to move toward the said lever in \Vltlt'll event the hooks 21. 2t" and 21" move away from the tongues 23 to liherate the doors. lnas nuu'h as the said hooks are o'l ditl'erent length the rest-iertive d ors will he sueeessivelv liherated at the various positions ol' the har l3. whi -h permits the earno in extends to one end ot the the variousportions between the partitions and the ends of the car to be dumped separately. The air supply pipe 20 may be engaged to the train pipe (not shown) and in this manner the dumping of the car may be effected from the locomotive, as will be understood. It is also understood that the piston rod 18 may be operatably connected to the bars 13 at both sides of the door whereby the respective opposite doors of the car are liberated simultaneously.

It will be seen that with the present invention that the tongues 23 may be of any suitable length to prevent them from slipping over the respective hooks to liberate the doors, Whereas the arrangement disclosed in the above mentioned patent ne cessitates the tongues being oi comparatively short length and thereby oceasionally slipping over the sliding bars to liberate the doors prematurelyl 1 What is claimed is:

1. The combination with a car plurality of doors hinged along thereof, tongues projecting from the free edges of the doors, a bar slidable along the respective side of the car arranged to en? gagethe tongues to retain the doors in c osed position and when slid to liberate the respective doors at various positions at the said oar.

hai'ing a one side l l l l l E l 5 The combination with a car having a plurality of doors hinged along one side thereof, tongues projecting from the edges of the said doors, a bar slidable along the respective side of the car, and hooks secured along the outer side of the said bar, the said hooks being of ditl'erent lengths and arranged to engage the tongues of the respective "doors to retain same between the said hooks and the bar, whereby upon the bar being slid the res; ective doors are liberated one at a time.

The combination with a car having a plurality of doors hinged along one side thereof. a bar slidable along the respective side of the car arranged to retain the door in closed position and when slid to liberate the respective doors at various positions of the said bar, a cylinder carried by the car,-a' piston Within the cylinder, a piston rod connected to the piston, an air supply pipe connected to the cylinder, and an operative connection between the piston rod and the said bar.

In testimony that I claim the foregoing as my own, I have hereto atlixed my signature in the presence of two Witnesses.
